TC-Helicon VoiceCraft Installation Guide - Manual (Page 8)

Troubleshooting
If there was a power failure, transmission error, or any other reason the
upgrade did not complete properly, turn the VoicePrism off and on. If the
old software is still present, you should see the main screen as usual.
Simply start the upgrade process from the beginning. If the unit powers
on and nothing happens, start the upgrade procedure by resending the
“ClearFlash.syx” file (step 19) and continue with the upgrade procedure
from there.
BIST (Built In Self Test)
1. On the VoiceCraft card, connect a cable from the S/PDIF input to the
S/PDIF output and from the AES/EBU input to the AES/EBU output.
2. Press the Power switch to turn on the VoicePrism.
3. Press and hold the Left Arrow, Preview and Store buttons within 3
seconds of power up until the LCD Display appears filled. Note:
VoicePrism will not enter BIST mode if there are cables attached to
any of the MIDI jacks on the back panel.
4. Confirm LCD moves through the following stages:
•
Filled
•
Full screen grid
•
Grid on right half of screen
•
Grid on left half of screen
•
Full screen grid
•
Automatic BIST status
Note: If the patterns do not appear in the order indicated, or if the
grid is incomplete, the unit fails the BIST. The above criteria
are only confirmed visually. No other indication is given.
5. Confirm the Automatic BIST status screen reads “PASS” beside the
following headings: FPGA, Address Bus, Flash, Audio ROM, Bit Bus,
RAM, EEPROM, 2181 DSP, EXP DSP, EXP RAM, EXP FLASH, VC
AUDIO.
6. The LCD indication should read “VISUAL CHECK”. If any of the
headings do not appear this also indicates a failure.
